Episode comments are ready for testing

I went to post a test comment on the V3 site:
- logged into the V3 Cat5.tv with my Cat5 user login
- wrote a small test comment on an episode
- went to post the comment
-> was prompted "Before we post this, who are you?" [prompt to login w/ email or social site]

Is this behavior by design? It occurred with Firefox 11.0 on both Ubuntu and Windows platforms.
